. Claims. or 169-2 1) This invention relates to improvements in fire engine ump assembly.

The main objects of this invention are:

First, to provide afire engine pump assembly which is adapted for embodiment in commercial types of trucks without substantial adaptation or reconstruction thereof.

,Second, toprovide a structure having these advantages in which the valve connection between the pump and the. delivery conduit is readily accessible for cleaning and may be easily removed and replaced without disturbing heavy of the invention will definitely appear from the description to follow. The invention is defined in the. claims. l

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in whichz Fig. 1 is a fragmentary plan view of an embodiment of the invention, only such portions of a truck or vehicle being illustrated as seen to be necessary to afford an understanding of the invention and the manner of adapting the same.

Fig. 2 is. an enlarged fragmentary view 2-2 of Figs. 1 and 3. y

Fig. 3 is a. horizontal section on line 3--3 of Fig. 2.

Fig. 4 is a. sectional view on a line corresponding to line 4-4 of Figs. 1 and 2.

Fig. 5 is a side elevation of the check valve and its casing.

In the accompanying drawing L-l represents the longitudinal sills of a motorvehicle chassis and 2, 2 the side walls of the vehicle body. The pump intake conduit 3 is mounted transversely of the chassis with its ends projecting through openings 4 provided therefor in the side walls 2. This intake conduit is provided with a connection 5 at either end for a hose 6 leading on line to a source of supply, a closure 1 being pro- 1 vided for the other end of the conduit. The delivery conduit 8 is disposed transversely of the chassis in laterally spaced relation to the inlet conduit. This delivery conduit is provided with a valve 9 at either end, only one being illustrated, and means In for connecting a hose thereto. These conduits are preferably formed with mounting brackets ll although it will be understood that they maybe otherwise mounted. They are fixedly supported, however. The delivery conduit is provided with a side inlet I2.

The ump, designated generally by the numeral I3, is designed to be driven from the motor vehicle, the driving connections not being illustrated. This pump is mounted on the conduits 3 and 8, but the details of mountingare not illustrated. The pump is provided with a discharge l4, the flanged end l5 of which is disposed adjacent to but in spaced relation to the inlet I2, see Figs. 2 and 3.

The casing l6 for the check valve l! is interposed between the end of the pump discharge l4 and the inlet l2 of the delivery conduit. This valve casing is preferably of uniform thickness, its sides being parallel so that it may be introduced between and removed from between the pumpdischarge and the delivery conduit inlet by a lateral sliding movement. It is secured in its adjusted position by means of the lag screws I8 which are arranged through the flange l5 on the end of the pump discharge l4 and are tapped into the walls of the delivery conduit. Gaskets I9 are arranged between the valve casing and the pump discharge and between the valve casing and the edges of the'conduit in let l2.

In use the check valves in this relation become fouled so that they do not function effectively for the reason that the source of water supply is frequently a ditch or stream, or other source in which more or less foreign substance is carried by the water. This feature of the ready removal of the valve permits the quick cleaning of the valve.

This apparatus may also be used generally as a pumping apparatus for pumping Water from ditches, flooded excavations or the like. With the parts arranged as provided for by this invention the valve may be easily removed for cleaning without disturbing the heavier parts and without the necessity of disconnecting the pump from its driving connections. A further advantage is that inasmuch as the intake and delivery conduits are arranged through the walls of the body it has heretofore been a difiicult and time consuming matter to remove the valve for cleaning and replacement.

We have illustrated and described the invention in a practical embodiment thereof. No attempt has been made toillustrate other adaptations which are possible as it is believed this disclosure will enable the adaptation of the invention as may be desired.

Having thus described our invention what 15 claimed as new and desired to secure by Letters Patent is:

1.
